I love this mattress! Thinking to change it for awhile and love this new one.
Hi very happy with my double medium bed I bought the base as well. Best things quick delivery free shipping. Had old bed well over twenty years if this last half that will be great value.
Way too soft.No edge supportLots of partner disturbanceWay too hot.My old mattress was 8 years old and was still better than this new one.I won’t buy again!
After doing some research and looking at many options we decided to go with the Sealy Advantage Cristal Medium King Mattress for so many reasons.The reviews were great, the mattress came in under budget and fit all of our needs.Very comfortable, well manufactured mattress, on the firmer side of medium but not uncomfortably so. I have a lot of back pain and now being pregnant, it has only increased and this has helped a lot.My fiancé has always preferred a more plush mattress but has said he’s sleeping a lot better now and doesn’t wake up aching anymore.So if you are on a budget, want a good quality mattress that ticks all the boxes from a reputable brand then this is the one!
Sealy Products are wonderful, and so are appliances on line. You can always rely on both. Highly Recommend Sealy bases and mattress.
The mattress is comfortable and I knew from Sealy it would be good quality,..love the fact that Appliances Online remove old mattress,...hassle free !!!!!
The listed size of this mattress was 240mm when it arrived it measured 280mm and is far to high for my needs making it difficult to get into bed as the total height including the base without the gliders is 600mm. Not good when you are only 5 ft tall.
Great bed. I bought this for my teenager son. He loves it. Just the right size and right comfort. The materials are breathable. The support is just right. I also bought the matching bed base. They work seamlessly together. Very happy shopping experience!
